Beeston Oil Fired Water Heater

[wcbsltd]

hi to all fellow engineers, i have recently taken on a beeston oil fired water heater(bit of a beast), I can't seem to get any info on the spares etc. all the info I have is; Beeston Heating (belgian plated) heater, NUM 21303, Anno 2001, Code 1242, Domestic hot water 325.5 litre. Output 90.1 kw with riello 40 G10 burner. I am currently looking for as much info on this as possible for future reference, however I do need urgent help on getting hold of expansion vessels for this boiler. dimensions/details of vessels; CIMM RP 8 LITRE rectangular vessel - 510x190x90mm with 3/4 male thread on top. 3 bar max. Hope someone can help, will keep looking aswell.

most expansion vessels are circular or cylindrical and are connected by male 3/4" thread
the Riello 40 G10 is a standard burner, data available from Riello
